How do I grant a program, after setting RMISecurityManager for the system, the permissions to read and write all of the System properties?

You have to grant the permission via the policy file. This looks like:

java.util.PropertyPermission "*", "read,write"

for using 
 
java.lang.System
  public static Properties 
      getProperties()
  public static void 
      setProperties(Properties props)

or:

java.util.PropertyPermission "{key}", "read"

for using 
java.lang.System
  public static String 
      getProperty(String key)
  public static String 
      getProperty(String key, String def)
You can also override following methods:
checkPropertiesAccess 
checkPropertyAccess

Thus enrolling your own "access policy".

Be sure to check the /guide/security/permissions.html from the Java 2 JDK documentation you are using.
